How not to do it (4)........

This is quite a common installation fault. The RPZ valve is situated too close to other objects, in this case its almost touching the ceiling above, which prevents the Accredited RPZ valve Tester from attaching the test equipment. Here the isolation valves have been turned through 90 degrees & once again no thought has been given to servicing or testing the RPZ valve, as they are pointing away from the tester. As a general rule we recommend that a minimum of 250mm is available above the RPZ valve for servicing & testing.

Its clear that the installer here, knows very little about RPZ valves & how to fit them correctly.
